If you look closely, the poor images appear to be the backsides of the legible front scans. The documents are only one sided, not two as in a book, the ink was heavy enough to show through when scanner programmed to scan both sides. Therefore, the unclear pages should be ignored, every other page would constitute the correct and clear pages.

One can hope that a better scan will be made.

One of the poorest scanned documents I have ever seen. It is very hard to read. Hope someone can get a hold of the original and make a better scan.
